What is a Multilayer PCB?
A Multilayer PCB is a printed circuit board that has more than 2 layers, unlike a double-sided PCB or a 2 layer PCB board, which only has two conductive layers of material. All multilayer PCBs must have at least three layers of conductive material.
A Multilayer PCB is much more complex than a double-sided PCB design and can have any number of conductive copper layers from 4 to 6 layers or even up to 64 layers. Multilayer PCBs are laminated and glued together with layers of heat protection insulation between them. The electrical connections between layers are achieved with various methods such as plating vias, through holes, and buried vias.
What is Gold Finger?
Gold fingers are the gold-plated connectors at the edge of printed circuit boards (PCBs). Shaped like a finger, they serve as connectors that connect the PCB to a motherboard, making sure a signal or command is reliably transmitted.
Before a printed circuit board can be built, it must be designed. This is accomplished using PCB circuit board design CAD tools. PCB design is broken into two main categories: schematic capture to create the circuitry connectivity in a diagram and then PCB layout to design the actual physical circuit board.
